Description

This application claims Paris Convention priority of EP 05 013 526.8 filed 23 Jun. 2005, the complete disclosure of which is hereby incorporated by reference.
BACKGROUND OF THE INVENTION
The present invention relates to a card reader with two rows of electric contacts in the form of elastically deformable contact springs for contacting the electric contact fields of a card which is inserted into the card reader, wherein the contact springs extend parallel to the card insertion direction, and wherein each contact spring comprises a contact section projecting into the card path for contacting one of the contact fields of the card, a connecting section for connecting to a write/read device, an intermediate U-shaped joining section and a mounting section for mounting the contact spring to the contact carrier, all being formed in one piece with the contact spring.
A card reader of this type is disclosed e.g. in EP 0 803 835 A2.
Each contact spring of this conventional card reader comprises a mounting section for mounting to the card reader housing, which is laterally or transversely offset from the contact and connecting sections of the contact spring and is inserted (shot) into a corresponding opening of the card reader. This transverse offset increases the space required by the contact springs in the transverse direction, and moreover transverse forces are generated between the contact and mounting sections when a card is being inserted, which could incline the contact section.
In contrast thereto, it is the underlying object of the present invention to reduce the space required by the contact springs of a card reader of the above-mentioned type, and effectively eliminate the transverse forces acting on the contact springs.
SUMMARY OF THE INVENTION
This object is achieved in accordance with the invention in that the contact section, the U-shaped joining section and the mounting section are symmetrical relative to the center plane of the contact spring.
When the connecting section is also symmetrical relative to the center plane of the contact spring, the space required by the contact spring in the transverse direction is minimized.
In a first, particularly preferred embodiment, the U-shaped joining section of the contact springs of at least one contact row is formed by two transversely spaced apart, parallel U-shaped arms which extend from the mounting section in a direction opposite to the card insertion direction, while the connecting section extends from the mounting section between the two U-shaped arms in a direction opposite to the card insertion direction. The mounting section of the contact spring is preferably formed like a frame and the contact section of the contact spring is disposed in the frame opening. The mounting section of the contact spring moreover preferably extends to a central web of the contact carrier, which is provided between the two contact rows.
In another preferred embodiment, the U-shaped joining section of the contact springs of at least one contact row is formed by one single U-shaped arm. The mounting section is preferably formed like a frame and the contact section of the contact spring is disposed in the frame opening. The mounting section of the contact spring moreover preferably extends to a transverse web of the contact carrier which is provided in front of the contact row, as viewed in the card insertion direction.
In advantageous embodiments of the inventive card reader, the U-shaped joining section of the contact springs of one or both contact rows faces in a direction opposite to the card insertion direction. In the latter case, the contact springs are arranged in the shape of a double-C, wherein the free ends of all contact sections face in the insertion direction and are not jolted but only resiliently deflected when a card is being inserted.
The connecting sections of the two contact rows preferably face away from each other.
Further advantages of the invention can be extracted from the description and the drawing. The features mentioned above and below may be used individually or collectively in arbitrary combination. The embodiment shown and described is not to be understood as exhaustive enumeration but has exemplary character for describing the invention.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 shows a longitudinal section through the inventive card reader with contact springs being arranged in the shape of a double C;
FIG. 2 shows a top view of the inventive card reader in the region of the contact springs; and

Reference numeral 1 of FIG. 1 designates a so-called push/pull card reader, wherein a user inserts a card 2 into the card reader 1 in the insertion direction 3 until the card abuts a card stop 4 in its data exchange position, and pulls it out again of the card reader 1 after data exchange. The card 2 has a microchip (not shown) for storing data, whose contacts are provided in the form of electric contact fields (not shown) on the card surface.
The card reader 1 has two rows 5 a, 5 b, disposed behind each other in the card insertion direction 3, of electric contacts in the form of elastically deformable contact springs 6 a, 6 b for contacting the electric contact fields of the card 2 inserted into the card reader 1. The contact springs 6 a, 6 b extend parallel to the card insertion direction 3 and are mounted to the card reader housing 7 which is an injection-molded plastic part.
Each contact spring 6 a, 6 b comprises a contact section 8 a, 8 b projecting into the card path, for contacting one of the contact fields of the card 2, a connecting section 9 a, 9 b for connecting a write/read device (not shown) of the card reader 1, an intermediate U-shaped joining section 10 a, 10 b and a mounting section 11 a, 11 b for mounting the contact spring 6 a, 6 b to the card reader housing 7, all being formed in one piece with the contact spring 6 a, 6 b. The contact section 8 a, 8 b is calotte-shaped and the connecting section 9 a, 9 b is formed as SMD contact.
The contact sections 8 a, 8 b and the U-shaped joining sections 10 a, 10 b of the contact springs 6 a, 6 b of both contact rows 5 a, 5 b are aligned in the same direction, i.e. the free ends of the contact sections 8 a, 8 b face in the card insertion direction 3, i.e. to the left-hand side in FIG. 2, and the U-shaped joining sections 10 a, 10 b are oriented in a direction opposite to the card insertion direction 3, i.e. are provided on the right-hand side. In other words, the contact springs 6 a, 6 b of both contact rows 5 a, 5 b are disposed in the shape of a double C, wherein the connecting sections 9 a, 9 b of the two contact rows 5 a, 5 b face away from each other.
As is shown in FIG. 2, the contact section 8 a, 8 b, the connecting section 9 a, 9 b and the U-shaped joining section 10 a, 10 b of each contact spring 6 a, 6 b are in the same plane extending at a right angle to the card path and card insertion direction 3. The contact, connecting and joining sections 8 a, 9 a, 10 a of a contact spring 6 a of one contact row 5 a and the contact, connecting and joining sections 8 b, 9 b, 10 b of a contact spring 6 b of the other contact row 5 b are thereby in the same plane.
As is shown in FIG. 3, the U-shaped joining section 10 a of the contact springs 6 a of the rear contact row 5 a, as viewed in the card insertion direction 3, is formed by two parallel U-shaped arms 12 a which are spaced apart in a transverse direction and extend from a transverse web 13 a of the mounting section 11 a in a direction opposite to the card insertion direction 3. The connecting section 9 a also extends from this transverse web 13 a between the two arms 12 a in a direction opposite to the card insertion direction 3, i.e. the connecting section 9 a is provided on the contact spring 6 a on the side of the U-shaped joining section 10 a. The mounting section 11 a is formed like a frame and comprises, in addition to the transverse web 13 a, also the transverse web 14 a and the two side legs 15 a, wherein the contact section 8 a is above the frame opening 16 a or, in the top view of FIG. 2, within the frame opening 16 a. The mounting section 11 a whose transverse web 14 a extends to a central web 17 (FIG. 2) of the card reader housing 7 provided between the two contact rows 5 a, 5 b, is an insert which is completely surrounded by injection-molded plastic material during production of the card reader housing 7. The contact section 8 a, the connecting section 9 a, the U-shaped joining section 10 a and the mounting section 11 a are symmetrical relative to the center plane of the contact spring 6 a, such that no transverse forces can be generated in the contact spring 6 a and the transverse dimension of the contact spring 6 a is minimized.
As is shown in FIG. 4, the U-shaped joining section 10 b of the contact springs 6 b of the front contact row 5 b, as viewed in the card insertion direction 3, is formed by one single U-shaped arm. The mounting section 11 b has the shape of a frame comprising the two transverse webs 13 b, 14 b and the two side legs 15 b, wherein the contact section 8 b is above the frame opening 16 b or within the frame opening 16 b as shown in the top view of FIG. 2. The U-shaped connecting section 10 b extends from the transverse web 13 b of the mounting section 11 b in a direction opposite to the card insertion direction 3, while the connecting section 9 b extends from the transverse web 14 b in the card insertion direction 3, i.e. is provided on the contact spring 6 b on the other side of the U-shaped connecting section 10 b. The mounting section 11 b whose transverse web 14 b extends to a further transverse web 18 of the card reader housing 7 is an insert which is completely surrounded by injection-molded plastic material during production of the card reader housing 7. The contact section 8 b, the connecting section 9 b, the U-shaped joining section 10 b and the mounting section 11 b are symmetrical relative to the center plane of the contact spring 6 b such that no transverse forces can be generated in the contact spring 6 b and the transverse dimension of the contact spring 6 b is minimized.
